## Main Question or Discussion Point

Hi all,

I would like to know if its possible and consistent to compose the global system matrix with different FEM elements such as frame, plane, shell solid etc... Theoritically all of them will have the same DOF per node just only comprising the local matrix will differ. And as long as we solve the linear algebraic systems with any methods that shouldnit do any harm at all.

Your comments will be appreciated.
